The early and middle stages of intrauterine pregnancy cannot be seen or detected through the method of tummy rubbing. The detection of pregnancy through tummy rubbing is mainly aimed at the middle and late stages of intrauterine pregnancy, which may be clearly indicated by palpation of the abdomen. If a relatively large abdominal mass is touched, it is possible to feel the corresponding fetal movement in the abdomen by touching it and see if there is a possibility of pregnancy, but this method is always not the most definitive method of diagnosis. For mid- to late-stage pregnancies, ultrasound monitoring is required to understand the enlargement of the uterus and the development of the fetus.
